The total syntheses of the antiinflammatory marine sponge metabolites (+)-cacospongionolide B and E are described. The pivotal steps in the synthetic route include a three-step sequence that couples the two main regions of the natural product, as well as generates the side chain dihydropyran ring. The activity of the synthetic analogues against bee venom phospholipase A 2 suggests that the cacospongionolides have enantiospecific interactions with the enzyme that may be independent of the γ- hydroxybutenolide moiety.
